ROWING APPARATUS.

Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed December 19, 1910. Serial N0.598,177.

To all whom it may concern:

Be it known that I, FERDINAND KAsnLow- SKY, a subject of the Emperor ofGermany, residing at Berlin, in the Kingdom of Prussia, German Empire,have invented certain new and useful Improvements in Rowing Apparatus;and I do hereby declare the fol-- lowing to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

Various apparatus are already known for rowing in the direction of onesview. All these apparatus, however, have the disadvantage, that theirattaching necessitates either extensive alterations in the boat itselfor that cars of unusual shape must be employed, to which the generalpublic will not get accustomed. The arrangements hitherto employedpartly also showed the danger of a piece of the clothing being caught inthe transmission gear. In the apparatus according to the presentinvention these disadvantages are obviated, by particular attentionhaving been paid toward employing oars of the usual shape, and that theattaching to the boat necessitated no constructional alterations to thesame. The car does not essentially differ from the pattern generallyemployed. Care has been taken that the transmission gears have beencompletely covered, so that there is no danger of the clothing or thelike getting caught or spoiled.

In the accompanying drawing a constructional form of the presentinvention is eX- emplified.

Figure 1 is a plan view of the apparatus. Fig. 2 is a side view of theapparatus, attached to a boat. Fig. 3 is a detail view showing thesocket into which the parts of the oar are inserted. Fig. 1 is a planView of a boat with a pair of oars made according to the presentinvention.

The oar is divided at the handle-end in two parts 1 and 2. Both partsare fitted into tubular sockets 3 and 4 to which are attached toothedsegments 7 and 8 engaging in each other and swiveling on pivots 5 and 6.Part 1 of the oar serves as handle part 2 is fitted with the blade. Thetwo toothed segments are arranged between two plates 9 and 10, Fig.2,which are held together by means of a U-shaped part 11, 12, the ends 18,14: of which are fitted with a male thread and are provided with collars15, 16, against which the lower plate 10 rests. Between plates 9 and 10distance pieces 17, 18 are fitted over ends 13, 1 1. The yoke of the U-shaped part 11 12 is arranged to swivel in a bearing 19, which has a pin20, with which it may be fitted into the thole-board of a boat similarlyto a common thole. For preventing the bearing 19 from turning on pin 20,the bearing is secured by means of two extensions 23, 2 1 provided withscrewclamps 21, 22 to the thole-board.

From the arrangement of the apparatus shown and described the reversemovement of the parts 1 and 2 when actuated is evident.

The present invention has the advantage, that it allows of turning theoar in a vertical plane, so that the oar may be dipped and raised out ofthe water in rowing.

I claim:

Apparatus for rowing in bow-facing position consisting of an oarcomprising two parts, said parts positively coupled with each other thattheir movements are reversed, the said parts of the oar fitted totoothed segments swiveling between two plates, the said plates heldtogether by means of a U-shaped part, the yoke of said U-shaped partswiveling in a bearing, said bearing provided with a thole-pin and screwclamps at both ends to prevent the bearing turning around saidthole-pin.

In testimony whereof I affix my signature in presence of two witnesses.

FERDINAND KASELOWSKY.
